Windows are able to make your basement appear more pleasing and improve safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Grand Rapids are built to permit more light into underground rooms than the older, smaller, rectangular windows that are added above ground. They also offer a way out in case of an emergency.
The main difference between basement, or egress, windows and standard windows is that basement windows are required to be made for an average-sized person to make it out in order to meet safety requirements set up in building codes. You are able to pick from appropriately sized casement, sliding or double-hung windows when you add basement windows. Be sure you totally understand local building codes before your purchase of basement windows.
